Specification of Letters Patent.

-EPatented March 1o, 1909.-

Application filed July '20, 1908'. Serial no. 44-135 5.

' T all whom it may concern:

tion sufficient to enable those skilled in t 1ev art to which itpertains to understand, make, and use the same.

This invention relates to what are known in the art as fireloss cookers,and the objects of the invention are to obtain a device which will beeffective in' operation, sanitary, economical in construction, sightlyin appearance, and durable; to obtain a device of the kind named whichis reversible, that is, a device provided with a base on which thevessels containing the articles to be cooked may beplaced and theremainder of thedes vice laced thereover, and also, a device in whicithe vessels containing articles to be cooked maybe placed and a coverplaced thereover.

A further object of the invention is to obtain a device from which noappreciable odor will escape when onions, and other like articles arebeing cooked therein.

In the drawing referred to Figure 1 illus- Qtrates a device embodyingthe invention, in vertical section, when used in such manner as to havea base-on which vesselsmay be set' and a body which may. be placedthereover. Fig. 2 illustrates ti e same construction illustrated in Fig.1 w on used with the body of the device in position to'forrn areceptacle in which vessels may be placed and the remainder of suchdevice being placed thereon to form acover to'the receptacle. Fig. 3 isa horizontal sectional view on line 33 of Fig. 1, viewed in thedirection indicated by the arrows. And Fig. 4 is a top plan view of adevice embodying theinvention. P

A reference letter applied to designate a given art is used to indicatesuch part throughout the several figures of the drawing, Whereverthesame appears.

A is the body art or portion of the device, B is a part of t e devicearranged to co-act with body art A, and constitutes a base on which theody part A is placed, when the device is used in the manner illustratedin Fig. 1, and a cover to the body part A, when l the device is used inthe manner illustrated inaFi 2. The body art A com rises the. cylinrical portion a, c osed at on a, suitable aching 6'] between the wallsof the cyl n n l and n port o s, n the. edg a at the open end .of suchcylindrical por tion. Edge 0/ is provided with the annular groove-C.

. The part or portion of the device which at times constitutes, the baseon which vessels,

tacle in which vessels are placed, is conconstructed embodying thisinvention 1 have 'made the annular groove (1 1n the part B, so

illustratedin Figs. 1' and 3., a raisedplatforni whioh' water may: heplaced heferesetting the body part A thereto.

The head D is arranged-to contact on the sides thereof with the sides ofthe groove-Q, but preferably the topof such bead does not groove, sothat when the device is used in the; manner illustrated in Fig. 2-, thewater which has been placed in such groove 0 bebead D in such groove,will not all be forced out from such groove, but some of such water willrema n in the groove. Water in will prevent odors passing out from theinterior of the device ,while articlesare cooki erein E is a mat,preferably made of wire, which I is placed on part B when the devioeisused in the manner illustrated. in Figs. 1 and 3. I find in practicethatwhenthe mat Eis with many interstices, an appreciable effect .isobtained, and that the heat is maintained ,for a given length of time ata higher temperature than when such mat Is not used. I attribute thisincreased effectiveness to the lessening of the conduction of heat fromthe i cooking vessel through part B by the interposition of said mat,constructed as described, between such vessel and such part B.

F is a belt of flexible material fitting to the cylindrical walls of thedevice and arranged to be placed over the joint produced ng position.

structed'with the annular beadD arranged. to fit into and co-Jact withthe annular groove- C. In the devices which I have'heretofore.

that when the dev oe is used in the manner (b will be obtained, and alsoachannel in om nt c nta t h he bo om h fore thepart B is placed on partA, with the annular groove d, or in annular groove C,

are placed and at times the cover to a recepe made of coiled Wire or ofmetal provided by ppttingthe parts A and B,.into operative coo Where thedevice is made of small size .it

made in large sizes it will be found con-' venient to use the device inthe manner shown in Fig. '2.- The strength of the person using thedevice will often determine the manner of its use.

The operation of this device is substantially the same as that of otherfireless cookers, to-wit, the article to be cooked, in a heatedcondition and in a suitable vessel is placed in the interior of thedevice, the device is closed, and allowed to remain in such closedcondition until the cooking is accomplished.

By constructing the edge a. of the body partA with an annular groove C,and the part B with the bead D to corres end with such groove 0, I findgreat rigidity is imparted to the parts, and. a device of considerablesize may be constructed with the certainty that a tight joint will bemade at all times in the use of the same, and the same will be durable.

The walls of the part A, at, the ends thereof which I have termededge'a, are joined by a sheet metal ring which is formed or stampedup'to obtain the groove C; and the co-actin part, attached to part B andprovided wlth bead D, is obtained in the same way. These parts may be opositely placed,

that is, the part provided wit 1 groove C may;

be attached to )art B and the co-acting part which is provided with thebead D may be attached to end a.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a device of the character described, a

additional part provided with an annular bead arranged to co-act withthe annular groove, and provided with an annular groove, such groovesarranged so that one thereof may contain water when the body part andthe additional part are joined; substantially as described.

2. In a device of the character described, a body part closed at one endand openjat the otherend, such cylindrical art comprising an-inner andouter wall, witli bad heat c'onducting material disposed between them,and

such walls connected at the open end of the cylindrical body art by aring which is curved on radial lines to obtain an annular roove on theedge of the open end, in combination with an additional part, suchadditional part provided with an annular bead arranged to co-act withthe annular groove,

ann ar groove adjacent to such bed, such grooves arranged so that onethereof may contain water when the body part and the additional part arejoined; substantially as described.

3. In a device of the character described, a body part closed at one endand open at the other end, such cylindrical art comprising an inner andouter wall, witii bad heat conducting material disposed between them,and

such walls connected at the open end of the cylindrical body art by aring which is curved on radial lines to obtain an annular groove on theedge of the 0 en end, in combination withan additiona part, suchadditional part provided with an annular bead arranged to co-act withthe annular groove,

and provided with a raised bed and anannular groove adjacent to theraised bed, such grooves respectively arranged so that one thereof maycontain water when the body part and the additional part are joined withthe body part underneath, and the other may contain water when the coveris underneath, and a mat provided with interstices arranged to beinterposed between such de vice and a vessel therein; substantially asdescribed.
